The popularity of Biometric Authentication bridged to the many innovation seen in this field. Biometric systems like finger print, retinal scan, face, voice, iris, signature and hand geometry are much in use and are transforming to wear and tear, due to its several drawbacks. Thinking in the aspect of uniqueness which keeps 85% away from failure is defined to be the new innovation in biometric which is the human body odour based bio-metric.

Most of the business processes and the companies like financial institutions which deals with huge data and monetary system demands a high authentication with security like never before. This gave rise to the highly successful personal identification which is the body odour bio-metric authentication.

A brief and a glance over the prevailing biometric systems which are been in use extensively and the short comings experienced.

Finger Print authentication one of the early innovation…

The pattern of fingerprint of an individual gets mapped in this system by comparing the ridges and furrows within the template. The fingerprint accustomed to the device initially examines at the high level in the database and then better comparisons with evaluation are delivered as outcome.

Shortfalls when discussed are that when affected by skin conditions and association with forensic applications the system fails its recognition.

It you think of speed, it proves with Iris and Retinal Scan biometric.

This is discovered as the fastest forms of biometric system. The iris and retina are scanned by a low intensity light source and the image is correlated with hoarded patterns in the database.

The shortfalls of this system is its high difficult to use and very intrusive, many would find it sensitive over using it.

Compares with your digital face template!

Something that embroils the scanning of entire face and critical points, the areas are checked and compared with the database stored which is the facial biometric.

Encounters few shortfalls and the prime drawback of facial scanning occurs between identical twins.

This does work good to prevent illegal authentication.

The accent, the rhythm and the stress differ from one person to another. The voice biometric is based on this concept.

Yes, does not serve with complete option as it requires large amount of storage and chances are the voice can change.

Something that has been improvised from finger prints is the Hand and Finger Geometry…

In affiliation with the fingerprint systems, the modern systems use this technique. It is based on the concept of overall dimensions of the hand, angle between the fingers and length, shape etc.

When talk about its drawback, it emits high equal error rate and does not prove good when applied on too young or too old people.

Here we are with the recent innovation and exploring the Odour Biometric System!

The most recent evolution in the biometric stream is the Odour Biometric System which is been brilliantly innovated based on the sniffing strategy. The so-called Electronic Nose or e-Nose is great to understand.

Recent analysis confesses the uniqueness of human odour. By then, like how dogs know several persons has exclusive and detectable body odour. When correlated with the other biometric systems it has the lower error rate of 15%. The main advantage is that it can never replicates human odour. Body odour exhibits strong authentication when compared with the other systems.

Due to the advancement in Sensor Technologies and improvements in the matching algorithms, make systems both secure and cost effective. Hence, the number of researchers has been identified as this the feasible system for personal identification.

Every Individual can be identified by their body odour which portrays the chemical composition. The Sensing System determines the odour from the environment. Gas chromatograph and spectrometer and array of chemical sensors are the types of sensing systems.

The National Institute for Medical research in London exposed as due to the natural body temperature, current of warm air surrounds the human body and it is relatively one third to one half-inch thick, and it travels up and over the body at a rate of 125 feet each minute.

So, the Researchers consider this technology could be used in airports, border checkpoints or anyplace where photo recognition is mandatory. In this domain, Odour Identification system is a peculiar idea and when carried out will strengthen the security systems. The pupil will never know he is been monitored. Therefore, this type of new sensors that allow the capture of body odour can provide a less threatening solution because the identification could be simultaneously captured while crossing the system and it does not require any special contact with the device.

It is definitely novel idea it saves time, saves cost over password authentication and this electronic nose system would soon be seen a great welcome in various government and industrial sectors.

Thank you for the excellent blog about the BIO-METRIC authentication especially the information about Human Odour authentication. I think, in future we could expect the further Electronic – Parts of Body like e-Nose.
